[MC-72762] 1.8 Server Crashing (com.google.gson.stream.MalformedJsonException)

My Minecraft server (downloaded from the website) crashes every time I try to start it up. I have downloaded different servers and they do the same. Here is the Crash Report:

Rename all JSON files in the server directory to see if the server runs after that.
If so, please attach the damaged JSON file.

PMann 2014-10-07T12:28:02Z

So I renamed all the JSON files, and when I started up the server it worked, but the 2nd time it started to crash again. How do I find the damaged JSON file?

Rename one JSON file after the other, when the server starts without crashing, the last file renamed was causing this. Then attach that file here.

PMann 2014-10-08T15:38:06Z

So I did as you requested, and it looks like every JSON file becomes corrupted when the server starts. I renamed one JSON file after the other, and when the server started without crashing it stayed on for about 5 seconds and then shut off. After that the server crashed once I would try to start it up. I'm still not sure that I am clear on how to find the damaged JSON file.

Does the server crash after 5 seconds or just shut down and the crash is at the next start of the server ?
Please rename / delete all JSON files, start the server, then attach the server.log here and all of the JSON files.

PMann 2014-10-09T13:13:08Z

It still will not allow me to copy the JSON files over into the comments to send them to you....

PMann 2014-10-09T13:22:19Z

Also, this time the server did not shut down automatically when I renamed the JSON files....and then once I shut it down and tried to start it up again it crashed.

kumasasa 2014-10-09T18:07:53Z

It still will not allow me to copy the JSON files over into the comments to send them to you....

???

Who't "it" ?

Out of ideas here.

PMann 2014-10-10T00:58:34Z

Here you go...My dad is an IT guy...I should have asked him sooner 🙂

PMann 2014-10-12T16:19:02Z

I gave you the JSON files....any news ideas?

kumasasa 2014-10-12T16:31:50Z

Nope. That aren't JSON files - they are named so, but the contents is no JSON.
Example:

Your ops.json

[jijn98]
[PManning4Prez]

My ops.json

[
  {
    "uuid": "212c6adb-6aad-4b04-ab21-0d52a98931c0",
    "name": "Kumasasa",
    "level": 4
  }
]

PMann 2014-10-13T15:25:19Z

So if these aren't the JSON files....which ones do you need?

kumasasa 2014-10-13T18:12:46Z

Didn't express clearly - sorry.

The files are the right ones, but the contents is crap. That's the bug and causing the crash.

PMann 2014-10-13T21:51:28Z

So what should I do to make them work? Is there a special way to type in the ops, whitelist etc....?

PMann 2014-10-14T14:02:23Z

Never mind, I figured it out. The server works now. Thank you very much for fixing this. 🙂

kumasasa 2014-10-14T14:57:45Z

Mind to share the solution ?

PMann 2014-10-15T15:56:35Z

I basically just deleted the old JSON files and started the server up again. Then I typed into the server commands /op PManning4Prez and /op jijn98 and it did it correctly for me. Then I banned who I needed to ban through the commands on the server...because I went through the server commands it set up the JSON files correctly.

Thanks again for the help

kumasasa 2014-10-15T18:14:24Z

Ok, thanks for the information. I still don't know the cause of that behaviour.

wobst.michael 2016-10-22T17:55:47Z

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time.
